LOCK'.

Appiieation filed November za'i'ezo. serial Ng. 425,620. v

rIhis invention .pertains more particularly to vtransmission vlever locks for vehicles,

chine or other structure toy which applied;l and such further objects, advantages andv capabilities as will vlater more fully appear.

My 'primary object is accomplished by providing aL pair of sleeves, one receivable within the other, one ot said sleeves being provided with a peripheral groove for the reception of a locking bolt carried by the other sleeve, the relation ofthe parts being such that'the outer sleeve can be turned on thel inner sleeve without injuring the parts.` I also make one ot the'walls ot the peripheral groove in the inner sleeve beveled or inclined, and the co-operating tace of the locking plunger likewise beveled or inclined so that if the-outer sleeve is vforced farther on to the inner sleeve than intended there Lwill not be any bending or springing of parts,

- because the locking bolt will ride up on the inclined face 'of the groove, and will Ybe forced backwardly, whereas it' the faces of both groove and plunger, or bolt, were at right angles and the outer sleeve were forced on farther than intended by the maker, there would be a tendency to bend the parts and thereby injure the lock.

My invention further resides in the combination, construction, and arrangement of 'parts illustrated in the accompanying drawings, and while I have shown therein a preerred embodiment, I desire the same to be understood as illustrative only and not as limiting my invention.

In the accompanying drawing illustrating my invention, Fig. 1 is a side elevation of a lock embodyingsaid invention, said lock being shown applied to the transmission lever. l

of an automobile; Fig-2, is a view taken at a right angle to Fig. 1; Fig. 3, is a vertical section taken substantially valong the plane indicated by line 3-3,.Fig. 2; Fig. 4 is a transverse section taken substantially along the plane indicated by the line 1 -4, Fig. 3. Y

Though in connection with a transmission lever, it is not .to be understood that it is applicable only to such use. Applied to a transmission my present invention is described lever 1 are innerand outer sleeves 2 and 3, the former of which is secured in Vpositon upon the transmission lever 1 by means of a pin or other vsuitable device 4. y 'This'outer sleeve 3 has` its lower peripheral ,edge beveled as at 3" to engage theupper beveled `rim of the-upper casing or plug 18'rigidly securedto' the usual transmission casing, the construction of which is well known and therefore not'illustrated. The inner sleeve is provided with -a peripheral Agroove 5, one.

wall, 6, of Awhichis inclined or beveled for a y purpose to be referred to later.- The 'outer sleeve 3 is hollow and adapted to slide on the transmission lever into a position surrounding thev sleeve 2. Mounted in the transverse opening 7 in the sleeve 3 is a key controlled lock 8, provided with la cam member 9 adapted to engage an'antifriction device 10 mounted upon locking bolt'll, which is slid# kable in an apetrure 12in slee-ve 3,'in a direction transverse to the'axis of thesleeve. EX#

tending transverselyv through plunger 11v is aI pin 13 the projectingends fof which are engaged by springs 14,. mounted in socketsin the outer sleeve. These springs cause bolt 11w to be projected inwardly into the groove 5 in sle`evev2, when said bolt'is reeto move.

A'head 17 on plunger 15 has resting against it one end `of spring 16 'which surrounds plunger 15 and has its other end resting against the inner side of the casing or sleeve 3. The upper end of plunger 15 is secured to lever 1 atl such a point that suhcient tension Will be placed On'the spring, when sleeve 3 is pushed downwardly into locking positon, to causethe sleeve, when unlocked, to 'rise .until entirely free from its cox-operating vlocking member as is well understood.

It should be knoted in passing that the locking bolt 11 or any equivalent structure may 1 drawing and the above description that when y bolt llis seated in groove' the outer' sleeve 3 may be turned by means of a wrench or otherwise without in any manner injuring the lock, which is what happensfwhen the plunger extends yinto a depression in the transmission lever or a separate sleeveV sei cured thereto, if said groove is not constructed topermit rotation as described. Injury of this kind sometimes happens when f thieves' attempt to` removea loci; or render it inoperative to hold the part from operation, thus permitting them to drive and con? trol the car'. The beveled edge of the groove and bolt permits the outer sleeve' to be tor'ced on farther than intended Without bending or springing any of the parts of the lock,

since rthe end of the bolt Would merely ride up on the inclined face of the groove thus shoving the bolt slightly A back into `its socket l2 until the bottom rof sleeve 3 comes to a complete stop againstcasing 18. It is ofcourse understood that the bolt lcan be used Without a beveled tace 'if desired, but

sleeve surrounding the iiXed sleeve and thevv lever, and cooperating With the transmission casing tolioldthelever against actuation, said slidablesleeve having a loclingmember and said locking member, and groove being constructed and arranged to cause the recession oi' said loclring'memberon abnormal sliding movement of said slidable sleeve toward said casing.; y Y* 2. In a transmission lock, a transmission casinghavng an open beveled m0uth a transmission lever movably mounted Within said casing, a `sleeve having a peripheral groove therein iixed to said lever, the upper face of saidy groove being approximately perpendicular to the axis of the `sleeve y'and the lower tace of said groove being inclined downwardly, a second sleeve slidable longitudinally of the first sleeve, said, second sleeve having a lower beveled edge adapted to contact the beveled mouth of said casing,

said second sleeve carrying a Alocking bolt provided With an A inclined face to Cooperate With the inclined -i-face ofthe groove whereby the second sleeve is permitted to advance on the first sleeve beyond normal locking positionvvithout yinjury to any of the lock parts.. 3. In an article of theclass described, in

combination With a casing surrounding a transmission lever and provided Withan open beveled mouth, an inner sleeve adapted to be rigidly secured to the lever, an outer sleeve surrounding and slidable along the lever Aand adapted to surround the inner sleeve and having a'lovver open end, the peripheral edge ot which is beveled and .adapted to contact the open mouth oi' said casing, said inner sleeve being provided With periphl eraldepression, and a ley-controlled loci(n ing adaptedtc engage the peripheral depression,

an upper Wall otsaid depression being per` pendicular to said leverand a lower Wall loi bolt mounted in the slidabley sleeve and said de ression slo inO obli uel Vtosaid les* p P e q y ver, said bolt having an upper Wall disposed in a plane parallel to the upper Wall of the depression and a lower surface 'disposedI` parallel to the sloping Wall of the depression.

In Witness whereof, I hereunto my name to this specification AUGUSTUS SAXTON.
